Their story
Brunimetal is a metal burnishing workshop founded at the end of 2017 in Manage, in the Belgian province of Hainaut. Our trade is burnishing: a chemical process that oxidises the surface of ferrous and non-ferrous parts. It works on the outer layer of the metal only, so the part is transformed on the surface and keeps its original physical properties.
We work with brass, copper, steel, aluminium, silver and gold, in a range of patinas and colours, from matt black to bronze. Everything is done by hand, for a high-end finish: each part is prepared and polished, immersed in our baths, rinsed, blown dry and left on racks, then protected by a final coat and wrapped in film, sealed with our own branded tape.
We support our clients through every stage of manufacturing, from preparing the parts to their final protection: even the simplest things deserve a tailor-made treatment.
In 2026 we launched BM Studio, a production workshop that puts our techniques and our spirit of experimentation at the service of artists, around burnishing and the processes that transform metal, to bring new collections to life. On 1 March 2026 it presented its collaboration with the designer Sébastien Caporusso, including the Saturn coffee table, in stainless steel, brass and copper.
